Improvement in suction-drills



UNITED STATES PATENT EEICE.

IMPROVEMENT IN SUCTION-DRILILS..

Specification forming part of Letters .To all whom it may concern:

Be it known that I, OWEN G. WARREN, of the city, county, and State of New York, have invented a new and useful Improvement in the Suction-Drill and I hereby declare that the following is a full and exact description thereof.

To enable others skilled in the business to make and use my invention, I proceed to describe its construction and operation, reference being had to the drawings hereunto annexed, and making part of this specification.

Figure lis a section of earth, showing a well in which is the suction-drill in elevation, with a rotary pump attached Fig. 2, vertical section of the pipe, 8vo., bothdesigns exaggerated as to the diameter ot' the pipe; Fig. 4, the curb representing any inclosure at t'op of the wellto hold Water 5 Fig. 3, section of the pipe; Fig.

5, lower end oi' the pipe-stock or socket for 4drill and the inlet holes.

Thesame letters refer to the same things in all the designs.

A is the pipe or hollow drill-shaftg B, the

drill-stock at the lower end; O, the drill; D, the cap E, the exhausting-pipe; F, a rotary pump; G, outlet-pipe; H, the curb at the top of the well; I, socket for the drill; K, inner part of pipe; L, section of the earth or rock bored into; M, the well or hole bored.

The purpose of this invention is,'whi1e drilling'in rock for petroleum, 8vo., to abstract the chips or comminuted stone or earth (the dbris of boring or stamping) com mingled with water by simply pumping it out. Anypump will do for the purpose. I propose to use a simple rotary pump that a man may turn by a crank -suc-tion may be made from a Patent 10.51.9841, dated January 9, 1866; antedatea December 26, 1865.

feet in height, through which the exhausting or suction pipe passes, or may pass, so as to let the Water oli' at a lower point than thesurface ot' water in the curb. The water will flow out through the suction-pipe in such case without pumping; but the pumping should go-on so as to give speed and forcible action to the water within the pipe. I

It' a valve be placedin the pipe, the motion of the drill will pump the water out, receiving it each time the pipe is thrust down; but a valve will do more harm than good if the well be iilled with water.

When power is used, so that it is not important to have the water How out easily, the point above the curb H, as shown, Fig. 1.

What I claim as my invention, and desire to secure by Letters Patent, is-

Exhaustin g the comminuted stone and dirt from a well through a pipe in the process ot' boring, in the manner substantially as above described.

' OWEN G. WARREN.'
